ENGLISH ABSTRACT: The policing and monitoring of South Africa's coastline and economic exclusion zone is made di cult not only by the size of the area of interest, but also by the limited resources available for maritime detection and policing. As a consequence, illegal activities, such as smuggling, poaching and illegal border crossings, are often conducted with impunity. Conventional approaches to monitoring coastal areas, such as the use of patrol boats, port inspections and aircraft surveillance, may be augmented by advances in technology that are steadily contributing vast amounts of data related to maritime activity. For example, various South African agencies collect auto- matic identi cation system and vessel monitoring system transmissions, and gather additional kinematic data of maritime vessels through a number of strategically placed coastal radars. A command and control centre for actively monitoring these data (outside of the intelligence community) was established by the South African Navy in 2014. Such centres provide surveillance operators with a real-time picture of a maritime region of interest from which they can identify relevant facts of interest through a reliance on experience and domain knowledge. The e ectiveness of this process may, however, be undermined by the vast quantities of data typically under consideration, by the di culty of identifying long-term trends in vessel kinematic behaviour and by the possibility of operator fatigue brought on by the relatively low incidence levels of activities of interest. E ective decision support tools may play a valuable role in this context by the automatic processing of these vast collections of data, by the identi cation of concepts of interest and by the prediction of future occurrences of interest. It is, however, essential that such tools should be exible enough to adapt to changes in typical vessel behaviour over time and that they should be capable of integrating new trends and new types of behaviours. Various approaches to maritime surveillance are investigated in this dissertation from the perspectives of threat detection and anomaly identi cation, with particular emphasis on a systems approach to decision support. A decision support system framework that utilises rule-based and data-driven mechanisms is proposed as a means to separate the interesting from the uninteresting and to provide early warnings of potentially threatening maritime vessel behaviour to operators. This system framework is primarily concerned with kinematic data and is restricted to the identi cation of certain types of activities. Successful classi cation and, ultimately, timely prediction of potentially threatening behaviour would allow for e ective policing by providing early warning to relevant entities, thus potentially leading to more e ective use of available policing resources.
AFRIKAANSE OPSOMMING: Die patrollering en monitering van die Suid-Afrikaanse kusgebied en gepaardgaande ekonomiese eksklusiewe zone word bemoeilik deur die grootte van die tersprake area en die beperkte hulpbronne wat vir patrollie-doeleindes aangewend kan word. Gevolglik gaan onwettige aktiwiteite, soos smokkelary, stroping en onwettige immigrasie dikwels ongestraf. Konvensionele benaderings tot die monitering van kusgebiede, soos die aanwending van patrolliebote, die uitvoer van hawe-inspeksies en gere elde lugpatrollies, kan aangevul word deur tegnologiese vooruitgang wat voortdurend tot groot hoeveelhede data oor maritieme aktiwiteit bydra. Verskeie Suid- Afrikaanse agentskappe ontvang byvoorbeeld outomatiese identi kasiestelsel en vaartuigmoni- teringstelsel uitsendings, en samel ook addisionele kinematiese data oor maritieme vaartuie deur middel van strategies-geplaasde kusradars in. 'n Bevel-en-beheersentrum wat hierdie inligting (buite die intelligensiegemeenskap) aktief ontleed, is in 2014 deur die Suid-Afrikaanse Vloot tot stand gebring. Sulke sentra verskaf 'n intydse blik oor die maritieme gebied onder beskouing aan operateurs wat dan, gebaseer op hulle ervaring en omgewingskennis, relevante inligting oor vaartuie kan a ei. Die doeltre ende uitvoering van hierdie proses kan egter ondermyn word deur die tipiese groot hoeveelhede data, die moeilikheidsgraad van die identi kasie van langtermyn tendense in die kinematiese gedrag van vaartuie om die kus en die moontlikheid van operateur-uitputting as gevolg van lang periodes van relatiewe oninteressante vaartuiggedrag. Doeltre ende besluitsteunhulpmiddels kan 'n waardevolle bydrae in hierdie konteks maak deur die ge-outomatiseerde prosessering van hierdie groot hoeveelhede data, die identi kasie van interessante vaartuiggedrag en die voorspelling van toekomstige relevante insidente. Dit is egter noodsaaklik dat sulke hulpmiddels buigsaam genoeg moet wees om te kan aanpas by veranderings in tipiese maritieme aktiwiteit oor tyd en dat nuwe tendense en tipes aktiwiteite geakkommodeer kan word. Verskeie benaderings tot maritieme oorsig word in hierdie proefskrif vanuit die perspektiewe van die bespeuring van bedreigings en die opsporing van vreemde verskynsels ondersoek, met 'n spesi eke fokus op 'n stelselbenadering tot besluitsteun. 'n Besluitsteun stelselraamwerk wat berus op re el-gebaseerde en data-aangedrewe meganismes word as 'n hulpmiddel voorgestel waarmee interessante maritieme gedrag van oninteressante gedrag onderskei kan word om sodoende 'n vroe e waarskuwing aan operateurs met betrekking tot moontlike bedreigende maritieme aktiwiteite te kan rig. Die werking van hierdie stelselraamwerk berus hoofsaaklik op die gebruik van kinematiese vaartuigdata en is beperk tot die naspeuring van sekere soorte bedreigende gedrag. Die suksesvolle klassi kasie en tydige voorspelling van potensi ele bedreigende maritieme gedrag behoort doeltre ende kusmonitering en verbeterde aanwending van die beperkte, gepaardgaande hulpbronne deur relevante kusagentskappe moontlik te maak.

Abstract:

This research studies the ability of 11 combat logistics force (CLF) ships and four transport aircraft to support building and sustaining operations at four maritime patrol and reconnaissance military airbases throughout the African continent. We have implemented a traditional hub and spoke (HandS) concept with sample demand data provided by the staff of Commander, Patrol and Reconnaissance Force Seventh Fleet, in a hypothetical situation where U.S. forces are required to assist the Nigerian government. We use the CLF Planner optimization tool to obtain shuttle schedules for three scenarios of daily demands of four commodities. One scenario requires the buildup of an airbase within seven days, and the other two require so in three days. All CLF shuttles have been randomly selected, positioned and loaded with commodities. Depending on the length of the buildup phase and the initial stock of commodities at the HandS, we find that the continuous sustainment operations (over a 45-day planning horizon) may not be feasible in some cases. Specifically, if a short buildup phase is required, we recommend the prepositioning of commodities at a minimum of 25% of daily demands, and dedicated air shuttles carrying only ordnance.

The logistics allocation program to evaluate the availability of resources (LAPEAR) presented in this thesis is a decision support system to aid NATO commanders in determining where to get resources to support a Multinational Maritime Logistics Force (MNLF). The problem is constrained by the structure of the desired logistics support organization and the amount of resources member nations are willing to provide in specific operation areas. For long range planning purposes, this model helps identify potential resource shortages in support of conflicts in specific operating areas. When a crisis situation develops, the model can help NATO commanders to quickly decide which nations should be tasked to provide resources. LAPEAR is easy to operate on a PC using the MS-DOS operating system and General Algebraic Modeling System (GAMS) modeling software with an associated solver. For realistic scenarios, LAPEAR provides optimal allocation plans in less than a minute.

Abstract:

Maritime logistics value (i.e. improving operational efficiency and service effectiveness in maritime logistics) is one of the strategic goals that maritime operators (i.e. port operators, shipping lines and freight forwarders) want to achieve. Due to the lack of a systematic approach towards maritime logistics management, however, existing literature has yet to clearly define what strategic direction should be taken to accomplish such goals. This thesis proposes that a knowledge-based strategy is the most desirable alternative, having diagnosed its effectiveness in creating and sustaining maritime logistics value. The thesis consists of theoretical and empirical sections. The theoretical part reviews the work of maritime logistics and operators within the context of global logistics and strategic management theory (especially, knowledge-based and inter-organisational relationship perspectives). The theoretical review clarifies the strategic objective of maritime operators, and highlights the importance of a knowledge management strategy towards such a business goal. Based on the literature review, the research develops a conceptual framework that shows the positive relationship between knowledge acquisition and maritime logistics value, and the role of social network embeddedness in acquiring knowledge. The empirical work undertaken to examine the conceptual relationship adopts a qualitative approach: an explorative case study and a Delphi survey. The explorative case study utilises an interview method with a semi-structured questionnaire, and two rounds of the Delphi survey are then conducted by collecting data from a panel of experts in the field. The two research methods are applied to the maritime logistics industry in Korea, where the strategic significance of maritime logistics value becomes ever more obvious. The empirical findings indicate that maritime operators acquire useful knowledge through being embedded in social co-operative and co-opetitive networks, and the acquired knowledge helps them to maximise the maritime logistics value. The work presented hereafter provides a meaningful insight for managers, policy makers and academic researchers into the knowledge management strategy and effective administration of a maritime logistics system in the context of interorganisational relationship. However, this thesis has not examined the way to apply the acquired knowledge on an internal basis of an organisation, and focuses solely on a qualitative approach. It is suggested that a quantitative and in-depth discussion on the knowledge-based maritime logistics research within an intra-organisational level be made by linking maritime operators’ strategy with macro-issues in global supply chains.

ENGLISH ABSTRACT: The increasing financial pressures exerted on ship owners in recent years due to cost inflation, overtonnage and low freight rates in many sectors, have forced ship owners to increase cost savings and contain costs. That induced certain shipowners to operate substandard ships. The cost advantages in substandard ships are through failing to maintain safety equipment and procedures, employing cheap and untrained crews, repairing only essential equipment on breakdown and register under flags that do not comply with all the international regulatory, economic and social requirements for ships. Those ships undercut the true costs of operating a ship and eventually drive the obedient shipowner out of the market at the cost of safe and clean seas. Because of the complex international environment in which shipping operates an international regulatory framework is needed to ensure safety at sea. This assignment gives a layout of that framework, which is co-ordinated by the International Maritime Organisation (!MO), as well as the ways in which it is implemented and regulated in individual countries, with reference to South Africa. The functioning of the South African Maritime Safety Agency (SAMSA), which has been established on 1 April 1998, is also discussed. The benefit of safe ports is highlighted and also the cost savings in marine insurance if ships are classified as safe. A brief description of the navigation instruments that SAMSA use to assist in achieving maritime safety is given. Finally, the diseconomies of substandard ships are debated against quality ships for cleaner seas.
AFRIKAANSE OPSOMMING: Die toenemende finansiële druk op skeepseienaars, as gevolg van koste inflasie, oortonnemaat en lae vragtariewe in verskeie sektore, het hulle gedwing om oor die laaste aantal jare hul kostes te beperk. Gedwonge kostebesparings gee aanleiding daartoe dat sekere skeepseienaars onveilige skepe bedryf. Kostevoordele in onveilige skepe word bereik deur veiligheidstoerusting en -prosedures nie in stand te hou nie, goedkoop en onopgeleide bemanning aan te stel, slegs die nodige herstelwerk aan toerusting te doen en deur te registreer onder vlae wat nie voldoen aan internasionale regulering, ekonomiese en sosiale vereistes vir skepe nie. Eienaars van sulke skepe, onderskruip die ware bedryfskoste van 'n skip en uiteindelik dryf dit die wetsgetroue skeepseienaars uit die mark ten koste van 'n veilige en skoon see. As gevolg van die komplekse internasionale omgewmg waann skeepvaart funksioneer, word 'n internasionale reguleringsraamwerk benodig om veiligheid ter see te verseker. Hierdie werkstuk gee 'n uitleg van daardie raamwerk, wat gekoordineer word deur die Internasionale Maritieme Organisasie (!MO), asook die manier waarop dit geïmplementeer en gereguleer word in individuele lande met verwysing tot Suid-Afrika. Die funksionering van die Suid-Afrikaanse Maritieme Veiligheids Agentskap (SAMSA), wat tot stand gebring is op 1 April 1998, word bespreek. Die voordele van veilige hawens word uitgelig, sowel as die besparings in maritieme versekeringskoste indien 'n skip as veilig geklassifiseer word. 'n Kort beskrywing van navigasie-instrumente wat SAMSA gebruik om maritieme veiligheid te bewerkstellig, word kortliks bespreek. Ten slotte, die dis-ekonomie van onveilige skepe word gedebateer teenoor die kwaliteit van skepe vir 'n skoner see.

Abstract:

This thesis aims to develop and validate the dimensions of supply chain collaboration and collaborative advantage in the containerised maritime industry and explores the impact of supply chain collaboration on collaborative advantage and port performance. Additionally, this thesis tests a mediation effect of collaborative advantage on the relationship between supply chain collaboration and port performance. This thesis employs a quantitative method. A theoretical model is built based on thorough literature reviews of supply chain management and maritime studies, in-depth discussions with experts, item review and Q-sorting techniques to signify ambiguity or misunderstanding with the scales and to suggest modifications. The proposed model is empirically tested with survey data using 178 responses from terminal operators, shipping lines, inland transport companies, freight forwarders, ship management companies and third-party logistics providers involved in maritime logistics in the major containers ports of Busan, Gwangyang and Incheon for a comprehensive and balanced view by using structural equation modelling. With regard to the findings of the empirical research, three main constructs were successfully validated as multi-dimensional constructs. The structural paths support hypotheses that supply chain collaboration has a positive influence on collaborative advantage, and collaborative advantage has a strong contribution to port performance. However, the direct impact of supply chain collaboration on port performance is insignificant. A hierarchical approach of the mediation test and bootstrapping test found that the association between supply chain collaboration and port performance is fully mediated by collaborative advantage. In other words, the greater degree of supply chain collaboration between the port and port user enables them to gain a higher degree of collaborative advantage, and, in turn, this collaborative advantage can contribute to augmenting port performance. This thesis synthesises transaction cost theory, resource based theory and a relational view to explain how supply chain collaboration influences collaborative advantage and port performance. Its theoretical contribution expands the concept of supply chain collaboration and collaborative advantage into containerised maritime contexts, capturing the perspective of the ports and port users. Further, despite numerous maritime studies which extol the importance of collaboration between the ports and port users, no systematic approach has previously developed and validated those constructs and relationships. The various maritime logistics organisations would benefit from applying the results of this study to their supply chain collaboration practices when seeking greater collaborative advantage. The results heed practitioners in containerised maritime logistics organisations to focus on balancing the facets of supply chain collaboration to transport flows of containers seamlessly and efficiently from door-to-door, as supply chain management philosophy drives the maritime logistics industry to become more integrated into shippers' supply chains.

Abstract:

The primary aim of this thesis is to develop effective solution techniques for large-scale maritime inventory routing problems that possess a core substructure common in many real-world applications. We use the term “large-scale” to refer to problems whose standard mixed-integer linear programming (MIP) formulations involve tens of thousands of binary decision variables and tens of thousands of constraints and require days to solve on a personal computer. Although a large body of literature already exists for problems combining vehicle routing and inventory control for road-based applications, relatively little work has been published in the realm of maritime logistics. A major contribution of this research is in the advancement of novel methods for tackling problems orders of magnitude larger than most of those considered in the literature. Coordinating the movement of massive vessels all around the globe to deliver large quantities of high value products is a challenging and important problem within the maritime transportation industry. After introducing a core maritime inventory routing model to aid decision-makers with their coordination efforts, we make three main contributions. First, we present a two-stage algorithm that exploits aggregation and decomposition to produce provably good solutions to complex instances with a 60-period (two-month) planning horizon. Not only is our solution approach different from previous methods discussed in the maritime transportation literature, but computational experience shows that our approach is promising. Second, building on the recent successes of approximate dynamic programming (ADP) for road-based applications, we present an ADP procedure to quickly generate good solutions to maritime inventory routing problems with a long planning horizon of up to 365 periods. For instances with many ports (customers) and many vessels, leading MIP solvers often require hours to produce good solutions even when the planning horizon is limited to 90 periods. Our approach requires minutes. Our algorithm operates by solving many small subproblems and, in so doing, collecting and learning information about how to produce better solutions. Our final research contribution is a polyhedral study of an optimization problem that was motivated by maritime inventory routing, but is applicable to a more general class of problems. Numerous planning models within the chemical, petroleum, and process industries involve coordinating the movement of raw materials in a distribution network so that they can be blended into final products. The uncapacitated fixed-charge transportation problem with blending (FCTPwB) that we study captures a core structure encountered in many of these environments. We model the FCTPwB as a mixed-integer linear program and derive two classes of facets, both exponential in size, for the convex hull of solutions for the problem with a single consumer and show that they can be separated in polynomial time. Finally, a computational study demonstrates that these classes of facets are effective in reducing the integrality gap and solution time for more general instances of the FCTPwB.

Abstract:

Maritime logistics plays a critical but often unnoticed role in global supply chains. Management of buyer-supplier relationships is central to the success of SCM. Therefore, as the essential part within the global supply chain relationships, it is important to study the inter-organizational relationships in maritime logistics network. The dominant consideration of relationship management research in maritime logistics has been focused on a dyadic level, and little research has looked at this issue from a network view. In addition, bringing about higher value through the process of complex exchange in business has been recognized, but seldom been examined empirically, neither has been the relevance between service complexity and the relationship strength. This thesis thus aims to explore the relationship structure and the value generated within the maritime logistics from a network perspective, mainly considering the service complexity within a varied of influential factors. Mixed methods approach has been adopted, using semi-structure interviews, quantitative questionnaire survey and social network analysis. The research framework based on logistics triad is established, and rich insights were obtained from industry. This leads to the evaluation of the relationship strength in maritime logistics networks, the association between service complexity and the nature of relationship in them, and the value generated in the networks, by using three-level analysis and six-dimensional measurement for relationship strengths. In terms of the major findings, this research identifies that not every link has the same level of integration in the network. A range of contingency factors affecting relationship strength are recognised. There is generally a positive correlation between service complexity and relationship strength, although some links do not demonstrate this. Likewise, there is an affirmative correlation between service complexity and value perceived. Nevertheless, only the values perceived by freight forwarders in each types of service are statistically significant. Until now, there has been very little consideration of using network perspective to measure and analyse the relationship dynamics and value generated in line with different service complexity in the maritime logistics, and therefore this thesis represents a clear contribution to the literature.

Abstract:

This study considers the impact of e-commerce technologies/software implementation on logistics capabilities and firm’s performance, particularly in the Malaysian third party logistics sector. As well as studying the impact of e-commerce, it is also interested in gaining knowledge on the current state of ICT and e-commerce adoption in this sector, and third party logistics companies’ perceived importance of the logistics changes in their industry resulting from the e-commerce revolution. The main tenet of this thesis is that e-commerce technologies implementation and its (higher) level of use strengthens logistics capabilities and stronger logistics capabilities are positively linked to a firm’s performance. The impact of e-commerce technologies implementation on the performance of the third party logistics companies is assumed in this study to be indirect, and, logistics capabilities is assumed to take on a mediating role. Data was collected using both survey and interview methods and then analysed using two main types of analyses: univariate (descriptive) and inferential (bivariate and multivariate). In general, connectivity is good among 3PLs as almost all the companies surveyed are connected to the Internet with various types of broadband access. The use of internal computer networks is also widely deployed with moderate to strong information systems infrastructure capability. Substantial ICT investments have been made as indicated from interviews with the 3PLs. The Intranet has been widely deployed as a tool to integrate internal business processes. However, the survey results suggest that logistics service providers in Malaysia are mostly late adopters with respect to the usage of web-based software systems, such as equipment and vessel tracking and collaborative logistics management systems, which have been around in the market for quite some time now. Relative adoption of online marketing and sales activities are low with the Internet mostly used for information and communication purposes, and not in or less so in marketing and sales processes. CRM is not widely deployed in the companies surveyed. The biggest driver for the uptake of e-commerce among the 3PL companies surveyed and interviewed is to speed up business processes while the biggest barrier was that data communication was too slow. The study of e-commerce impact on logistics capabilities and the performance of a firm shows that there is a positive effect of e-commerce software systems on both. More importantly, logistics capabilities have been shown in this study to function as a mediating variable providing support to the hypothesis that e-commerce software systems has an indirect effect on firm’s performance. Empirical results also suggest that certain performance can be enhanced through strengthening of specific logistics capabilities. For example, strengthening information flow management capabilities would strengthen or enhance the company’s performance in the areas of order cycle time variability, processing accuracy, perfect order fulfilment, planning accuracy, availability of information, and systems malfunction recovery. Results from this study show that the 3PL companies did not consider the logistics changes as significant, except for those that concern information flow to the customers. In fact, most of the logistics changes proposed as important and significant in the literature (these were included in the questionnaire) were not even considered as relevant to the third party logistics industry in Malaysia.

Abstract:

Focus of this bachelor thesis is on examining the port located in Köping, thus a holistic view of maritime transportation is adapted in relation to the examined companies in the region and their global trade. The aim of this study is to examine the current situation and the potential to increase transportation of goods by maritime transportation and what criteria are the most important for different industrial/customer segments. The aim is divided into three research questions: • RQ1: Which decision criterions are considered in selection of transportation mode? • RQ2: What are the advantages and the disadvantages of the different transportation modes? • RQ3: When is maritime transportation preferable to road and railway? The research approach used in order to answer the aim and research questions were; literature review to gain an understanding of freight transportation in a broad context. To narrow down the area, freight transportation practice in the Swedish setting have been examined. Data collection for the Swedish setting have been collected through reports published by the national authorities. Lastly, data for freight transportation in the region of Western Mälardalen has been collected through a case study.Several criterions were found to be of importance during a transportation mode decision, as well as interrelationships between criterions. The identified criterions were cost, reliability and time, frequency and volume and lastly specific goods need. This was found to be in line with theoretical framework, especially the fact that the mode decision is vastly complex and highly depended upon which industry is making the decision, that is the context. A comparison of the modes was made to specify the benefits and downfalls with each mode for answering research question 2. Furthermore, an important identification is the gap between transportation purchaser and providers view of the reliability criterion. This difference can create a gap making it difficult to attract customers to maritime transportation. It is recommended that a thorough investigation is needed in order to examine what aspect of reliability is achievable and realistic in maritime transportation in general and for Köping´s Port in particular.

The movement of supplies from ship to shore to support military forces in or near combat areas has historically been difficult and time consuming. The Marine Corps and the Army have developed their own systems for satisfying their logistical needs. The Marine Corps has embraced the prepositioning concept, while the Army has relied on moving forces and utilizing logistics over the shore capabilities. Regardless of the offload method used, the efficient delivery of containerized cargo and equipment is critical to the establishment of forces ashore. During May 1992, a Maritime Prepositioning Force (MPF) and Joint Logistics Over the Shore (JLOTS) exercise was conducted at Onslow Beach, North Carolina, to test these delivery systems. Ocean Venture '92 provided a low- to mid-intensity platform for examining MPF and JLOTS capabilities. This thesis presents the organizations and equipment requirements for MPF and JLOTS operations and assesses the effectiveness of Ocean Venture '92 with respect to accomplishing key objectives, problem identification, lessons learned and recommendations for improving future MPF and JLOTS operations.

ENGLISH ABSTRACT: Liner shipping supplies a frequent scheduled transport service between designated ports to meet the needs of importers and exporters. Those needs are becoming more specific as a result of increasing competition attributable to globalisation of trade while importers and exporters are requiring more exacting services from the liner operators. The elements of service which most concern the importers and exporters are obviously the costs they must bear for the conveyance of the cargo and the time taken for its delivery. In order to meet the requirements of importers and exporters and at the same time enable the operators of the services to remain in business in the face of increasing competition within the industry, liner shipping worldwide is undergoing major changes. These changes are intended to increase the economies of scale and to extend control of the liner operators over the landside transport services. A discussion on liner shipping and current developments is contained in Chapter 3. Liner shipping plays an indispensable role in the economy of South Africa because almost 50% by value of South African imports are containerised. That equates to 8% of South African imports by volume (Moving South Africa: 1998), although it must be borne in mind that some of the cargo moving through South African ports is ultimately destined for countries in SADC (Southern African Development Community). According to Drewry Shipping Consultants, containerised cargo worldwide has been growing at the rate of about 8% per annum since 1980 and the South African trade has experienced a similarly high growth. The actual transport of containers, by sea is only one of the elements in the transport logistics supply chain (TLSC) between exporters in one country and importers in another with which liner operators must concern themselves. A conceptual background explaining the entire TLSC is provided in Chapter 2. In that chapter, the TLSe is defined and two models are used to identify key elements of the TLSC as well as interaction between them. Inefficiencies existing in individual elements of the TLSC as well as suggested solutions to the underlying problems are discussed in Chapter 4. Emphasis is placed on the need to use information technology as a vehicle to integrate the individual elements of the TLSe and as a means of saving costs and time. A discussion of the economic benefits of an efficient TLSe is contained in Chapter 5, while Chapter 6 includes a discussion on local and regional developments that have a bearing on the efficiency of the TLSe. The conclusions of the study together with recommended action are contained in Chapter 7.
AFRIKAANSE OPSOMMING: Lynvaart bied 'n gereeld geskeduleerde vervoerdiens tussen bepaalde hawens om in die behoeftes van in- en uitvoerders te voorsien. Weens toenemende mededinging voortspruitend uit die globalisering van handel, raak hierdie behoeftes egter al hoe veeleisender, terwyl in- en uitvoerders ook al hoe meer eise begin stel aan die gehalte van die diens wat deur lynvaartoperateurs gelewer word. Die elemente van hierdie diens waarby in- en uitvoerders die grootste belang het, is uiteraard die koste en die tyd verbonde aan vragverskeping. Om aan die vereistes van in- en uitvoerders te voldoen en dit terselfdertyd vir operateurs moontlik te maak om hul besighede te midde van toenemende mededinging in die industrie te bly bedryf, is die lynvaartbedryf wereldwyd besig om groot veranderinge te ondergaan. Hierdie veranderinge is bedoel om skaalvoordele te verbeter en lynvaartoperateurs se beheer oor vervoerdienste aan land uit te brei. Lynvaart en huidige ontwikkelinge in die bedryf word in Hoofstuk 3 bepreek. Lynvaart speel 'n onontbeerlike rol in Suid-Afrika se ekonomie omdat ongeveer 50% van die waarde van Suid-Afrika se invoere in houers vervoer word. Dit is gelyk aan 8% van Suid-Afrika se invoere per volume (Moving South Africa: 1998), alhoewel daar ook in gedagte gehou moet word dat 'n gedeelte van die vrag wat deur Suid-Afrikaanse hawens beweeg, uiteindelik bestem is vir lande in die SAOG (Suider-Afrikaanse Onwikkelingsgemeenskap). Volgense Drewry Skeepskonsultante, groei die vervoer van houerverskeping sedert 1980 teen 'n tempo van ongeveer 8% per jaar, en het die Suid-Afrikaanse handel 'n soortgelyke hoe groeikoers ondervind. Die werklike verskeping van houers is net een van die elemente in die vervoerlogistiekvoorsieningsketting (VL VK) tussen uitvoerders in een land en invoerders in 'n ander land waarmee lynvaartoperateurs rekening moet hou. 'n Konseptuele raamwerk wat die VLVK in die geheel verduidelik, verskyn in Hoofstuk 2. Die VLVK word ook in hierdie hoofstuk gedefinieer en twee modelle word gebruik om elemente daarvan asook die interaksie tussen daardie elemente te identifiseer. Die ontoereikendheid van individuele elemente van die VLVK asook moontlike oplossings vir die onderliggende probleme word in Hoofstuk 4 bespreek. Klem word geplaas op die noodsaaklikheid om informasietegnologie te gebruik om die individuele elemente van die VLVK te integreer ten einde tyd en koste te bespaar. Die ekonomiese voordele van 'n doeltreffende VLVK word in Hoofstuk 5 bespreek, terwyl Hoofstuk 6 handel oor plaaslike en streeksonwikkelinge wat die VLVK se doeltreffendheid beinvloed.

Resumo: Este trabalho aborda um problema de planejamento tático em empresas de transporte marítimo de carga que coletam e entregam as demandas contratadas por seus clientes. As viagens associadas a estas demandas são obrigatórias, mas a empresa pode também atender a demandas spot associadas com viagens opcionais para aumentar seu lucro durante um horizonte de tempo de médio prazo. O problema de otimização é formulado como um modelo de programação inteira mista que é definido em um grafo orientado em que nós representam viagens obrigatórias e opcionais. As decisões do modelo são determinar o número e tipo de navios que compõem a frota, designar um navio a um conjunto de viagens obrigatórias e opcionais, definir as rotas de cada navio e estipular os tempos de início de atendimento nos portos para cada viagem. Um algoritmo de busca tabu com uma lista de candidatos e um conjunto de soluções de elite são propostos para resolver instâncias do problema. Os resultados computacionais da busca tabu são comparados com as soluções ótimas e sub-ótimas encontradas pelo CPLEX para o modelo de programação inteira mista
Abstract: We address a tactical planning problem faced by many liner shipping companies that have committed contractual voyages while trying to serve optional spot voyages to increase its revenue over the medium-term horizon. The optimization problem is formulated as a mixed integer programming model that is defined on a directed graph whose nodes represent contractual and spot voyages. The decisions include the number and type of vessels deployed the assignment of vessels to contractual and spot voyages and the determination of vessel routes and schedules in order to maximize the profit. A tabu search algorithm with a candidate list and a pool of elite and diverse solutions is proposed in order to solve a set of benchmark instances of the problem. The results obtained by tabu search are compared to optimal and suboptimal solutions yielded by the CPLEX solver to the mixed integer programming formulation of the problem

Abstract:

The overarching objective of this thesis is to explore the role of logistics service quality in generating customer loyalty by considering relationship quality and switching barriers in the unique context of maritime transport. This is to fill the gaps revealed in the current understanding of ocean carrier-shipper relationships, particularly the lack of studies attempting to investigate shippers' future intentions to use the same carrier as opposed to the many previous studies which focused on carrier selection criteria or on shippers' satisfaction with the service attributes. Specifically, this research develops a conceptual model in order to determine how and to what extent Logistics Service Quality (LSQ) and Relationship Quality (RQ) towards Customer Loyalty (CL) are related and examine the moderating role of Switching Barriers (SB). By dividing these major concepts into sub-constructs (i.e. LSQ-operational logistics service quality and relational logistics service quality, RQ-satisfaction, trust and commitment, CL-attitudinal loyalty and behavioural loyalty, and SB-switching costs, attractiveness of alternatives and interpersonal relationships), more sophisticated interrelationships are able to be explored. The overall research design adopted in this thesis is as follows. First, the coherent research model representing causal relationships between the key variables is developed on the basis of a literature review and semi-structured interviews with practitioners and academics. Secondly, the main data used is collected through a postal questionnaire survey from 227 freight forwarders doing business with container shipping lines in South Korea. Structural Equation Modelling (SEM) is employed in order to rigorously test the validity of the measurement models and examine the extensive set of relationships between the construct variables simultaneously in a holistic manner. The findings of this research demonstrate significant contributions of logistics service quality in predicting customer loyalty through relationship quality in the maritime transport context. The interrelationships between the sub-constructs of these concepts are also confirmed. In addition, difference in the hypothesised relationships is highlighted depending on switching barriers. In conclusion, the thesis extends the body of knowledge in maritime transport, logistics/SCM and relationship marketing particularly in the business-to-business context by suggesting that container shipping lines should develop a high level of logistics service quality and relationship quality and also should utilise switching barriers in order to attain higher (beyond mere satisfaction) levels of shippers' loyalty.

Abstract:

This thesis focuses on the significance of distributive space for understanding capitalist forms of spatio-temporality. It argues that the distributive phase of commodity mobilities has remained a relatively under-represented aspect of social theory, especially in the context of cultural and social geography. The extant work that has focused on distribution tends to be confined to the areas of economic and transport geography. The thesis aims to address the importance of this space for understanding the formations of late capitalist modernity, particularly its role as a specific, but networked space between production and consumption. Significantly the work addresses the 'construction' of this space by focus sing on the substantive case study of containerisation. In doing so it engages with global commodity mobilities in the form of intermodal shipping containers, and their attendant logistical infrastructure. The research critically considers the spatial and temporal apparatuses that have been developed to organise and order the mobilities of the containers; including the design and development of the object itself, alongside a range of logistics and supply chain management strategies. In theoretical terms an important influence on the research has been Michel Serres' work on the interlacing of order and disorder. Given this, a simultaneous focus of the research deals with the immanent presence of disorder in these systemic environments; thus reflecting an intellectual engagement with theoretical work in the areas of turbulence, complexity theory, assemblage theory and Serres' work on the parasite. Substantively this aspect of the research has been determined by considering the place of the accident within networks and systems, alongside the 'tactical-logistics' of smuggling practices. 3

Abstract:

A importância do transporte aquaviário é dada pelos diferentes modos de navegação, podendo ser por meio fluvial, lacustre e navegação marítima. Para a logística e economia brasileira, este é um modal extremamente importante, haja vista a pluralidade de transporte pelo fato das relações de exportação e importação ocorrerem especialmente por este tipo de modal. No Brasil há cinco modalidades de transportes: o aquaviário, o rodoviário, o aeroviário, o ferroviário e o dutoviário. Serão descritas nos próximos capítulos as características de cada tipo de modal, especificamente dos modais rodoviário e aquaviário, em especial a cabotagem, objeto principal deste estudo. O objetivo deste trabalho é analisar a atual situação do transporte marítimo no Brasil, especialmente a cabotagem. Através de três parâmetros - custos, tempo de viagem e segurança -, procurar-se-á avaliar o nível de qualidade do modal, visando à identificação da existência de pontos críticos e sugerir possíveis soluções baseadas na logística e na tecnologia, ferramentas fundamentais para a busca da eficácia na redução dos custos de transportes, contribuindo para um melhor resultado dos custos logísticos finais. Para uma reflexão sobre o transporte nacional de mercadorias por via marítima através da cabotagem, serão apresentadas as características principais do transporte marítimo, com suas vantagens e desvantagens e sua importância para a economia brasileira. A crítica envolverá a questão do frete marítimo e suas interrelações, discutindo variáveis que compõem o preço do frete. Ferramentas tecnológicas fundamentais para a eficácia das operações também serão abordadas durante este trabalho. Serão descritas as características dos portos brasileiros, em especial as dos portos do Rio Grande (RS), Santos (SP), Suape (PE) e Rio de Janeiro (RJ), a distancia entre o porto do Rio de Janeiro (RJ) e os demais, bem como o tempo de viagem relacionado entre eles. Explorado pela União diretamente ou mediante concessão (precedida de licitação), o porto organizado, construído e aparelhado para atender necessidades da navegação e da movimentação é administrado pelo Conselho de Autoridade Portuária - CAP -, contando ainda com a figura do OGMO Orgão Gestor de Mão de Obra que controla a força de trabalho nas áreas portuárias, organismos instituídos pela Lei n. 8.630, de 25 de fevereiro de 1993, chamada da Lei de Modernização dos Portos. Por fim serão analisadas as variáveis custo, tempo de viagem e segurança no intuito de contribuir para uma reflexão para o crescimento do transporte de cabotagem no Brasil, procurando identificar um ganho substancial na economia brasileira, através da economia de escala, observados todos os parâmetros necessários para o bom desenvolvimento da logística de transporte de mercadorias por via marítima. Este trabalho abordará a Gestão do Transporte Marítimo de Cargas no Brasil, em especial a cabotagem.
The importance of water transport is given by different modes of navigation can be by river, lake and sea. For the logistics and the Brazilian economy this is a very important shift, given the plurality of transport because of the relationship of exports and imports occur especially for this type of shift. In Brazil there are five modes of transport, water transport, road, aviation, rail and pipeline. Will be described in later chapters the characteristics of each type of shift, specifically the roadway and water transport, in particular cabotage, the main object of this study. The objective of this study is to analyze the current situation of transport in Brazil, especially the coasters. By three criteria, costs, travel time and safety, an attempt will be to evaluate the quality of the shift in order to identify the existence of critical points and suggest possible solutions based on logistics and technology, key tools for search effectiveness in reducing transport costs, contributing to a better outcome of the final logistic costs. For a reflection on the national transport of goods by sea by cabotage, will present the main characteristics of the sea, with its advantages and disadvantages and its importance for the Brazilian economy. The criticism will involve the issue of freight and discussing its relationship variables that make up the price of shipping. Technological tools essential for efficient operations will also be addressed during this work. We will describe the characteristics of the Brazilian ports, in particular the ports of Rio Grande (RS), Santos (SP), Suape (PE) and Rio de Janeiro (RJ), the distance between the port of Rio de Janeiro (RJ) and other as well as the related travel time between them. Operated by the Union directly or through concessions (preceded by auctioning), organized port, built and equipped to meet needs of shipping and handling is managed by the Port Authority - CAP - and we also have to figure OGMO - Organ Manager Labor, which controls the work force in the port area, the bodies established by Law No. 8630 of 25 February 1993, called the Law of Modernization of Ports. Finally the variables will be considered cost, time travel and security in order to contribute to a reflection on the growth of cabotage transport in Brazil, trying to identify a substantial gain in the Brazilian economy, through economies of scale, observed all the necessary parameters for the proper development of the logistics of transporting goods by sea. This paper will address the Management of Maritime Carriage of Cargo in Brazil, in particular cabotage.

Abstract:

Arsenal secondaire de la Royale au XIXe siècle, Rochefort demeure pourtant, dans la continuité du siècle des Lumières, une base navale dévolue au ravitaillement des colonies. Insérée au sein du réseau des ports-arsenaux de l’État, la cité charentaise demeure un lieu de concrétisation de la politique coloniale de la France. Jusqu’à la Première Guerre mondiale, son arsenal prépare ainsi des cargaisons destinées aux possessions françaises dans les Amériques, en Afrique, en Asie et dans l’océan Pacifique. S'embarquent aussi de Rochefort et des autres ports de guerre et de commerce dans le cadre de son service colonial des milliers de passagers destinés aux outre-mers : administrateurs, officiers, soldats, colons, familles et domestiques ou encore religieux et condamnés. À l’inverse, l'arsenal est également un port de retours et d'arrivées en métropole. L’ampleur de la tâche demande en conséquence une mobilisation constante. Infrastructures portuaires, navires et réseaux d'approvisionnement sont utilisés au mieux de leurs capacités, faisant de l'arsenal de Rochefort un des centres de la logistique coloniale de l’époque. L'objet de ces travaux est donc de mettre en lumière, à partir d'un corpus documentaire riche mais trop peu exploité, cette mission singulière qu’est l’apport de soutien aux colonies depuis un arsenal de rivière comme celui de Rochefort. Il s’agit aussi de voir comment rejaillissent ses activités navales et coloniales sur une ville garnison liée au ministère de la Marine et des Colonies. Enfin, cette thèse s’attache à montrer l'importance de la logistique dans la constitution de l’empire colonial français
Secondary arsenal of the Royale in the 19th century, Rochefort nevertheless remains, in the continuity of the Age of Enlightenment, a naval base devoted to supplying the colonies. Inserted within the network of ports-arsenals of the State, the city of Charente remains a place of concretization of the colonial policy of France. Until the First World War, its arsenal thus prepared cargoes intended for French possessions in the Americas, Africa, Asia and the Pacific Ocean. Thousands of passengers destined for overseas also embarked from Rochefort and other war and commercial ports as part of its colonial service : administrators, officers, soldiers, settlers, families and servants or even religious and convicts. Conversely, the arsenal is also a port for returns and arrivals in mainland France. The magnitude of the task therefore requires constant mobilization. Port infrastructure, ships and supply networks were used to the best of their abilities, making the Rochefort arsenal one of the centers of colonial logistics at the time. From a rich but too little exploited documentary corpus, the purpose of this work is therefore to highlight this singular mission of providing support to the colonies from a river arsenal like that of Rochefort. It is also a question of seeing how its naval and colonial activities reflect on a garrison town linked to the Ministry of the Navy and the Colonies. Finally, this thesis aims to show the importance of logistics in the constitution of the French colonial empire

Abstract:

A gestão de um recurso para se obter a sua máxima ocupação requer não somente a técnica de planejamento adequada, mas também a consideração das incertezas durante o seu uso. Este trabalho utiliza o ponto forte das duas principais vertentes da pesquisa operacional: otimização e simulação em um contexto logístico portuário. Portanto, a técnica de programação de produção aplicada a um sistema logístico, associada à flexibilidade das aleatoriedades inerentes ao mesmo processo, provê aos tomadores de decisão de sistemas portuários um modelo matemático que auxilia na melhor ocupação de um canal de acesso aos terminais portuários. Assim, foi desenvolvido um modelo de otimização, inspirado no \"job shop\" aplicado em um sistema logístico, capaz de propor, partindo de um conjunto de navios, a melhor programação de acesso ao porto, através das informações relacionadas às operações portuárias. Uma vez estipulada a melhor programação, ela foi testada em um modelo simulação contemplando todas as etapas de um processo de carregamento/descarregamento de um navio em um terminal portuário, incluindo as incertezas de cada uma das etapas, bem como disponibilidade de ativos, regras de cruzamento e movimentações no canal. Através desta modelagem híbrida, obteve-se uma avaliação realista da proposta gerada pelo otimizador com a apuração dos resultados utilizando indicadores de desempenho atualmente empregados por profissionais de sistemas portuários como ocupação do sistema, tempo em fila e tempo de estadia do navio. Assim, foram comparados os impactos na mudança da forma de se operar um canal (liberando ou não o cruzamento dos navios durante seu curso) e calculados os ganhos operacionais de se programar os navios em sua entrada ao invés de simplesmente respeitar a ordem de chegada das embarcações.
The resource management in order to reach its maximum occupation requires not only the appropriate technique, but the incorporation of the uncertainties built in the process. This research uses the strength of each main streams of Operations Research: optimization and simulation in a logistic maritime context. Hence, the scheduling technique applied in a logistic system, and associated to the flexibility of having the uncertainties of its process provides the maritime logistic decision makers a mathematical model that helps them to deliver a better occupation rate of the canal to access the port terminals. To accomplish such objective, it was developed an optimization model, inspired in the job shop problem, and applied in a logistic system capable to propose, from a ship list, the best schedule, changing the order of entrance and exit of the vessels, using information related to its port operations. Once the best order of vessel is found, it was tested in a simulation model with most of constraints incorporated including all steps of the process, loading/unloading process, and all uncertainties within each step of the process (resources availability, navigation rules, safety, and operations policy). Such hybrid modeling technique, it was achieved a realistic evaluation of the optimization proposition, with the results measurements well known by the port practicioners, such as occupancy rates, waiting time, and complete service time (Makespan). To reach such evaluation it was compared the impact of changing the operations policy of the canal (allowing or not the crossing of the ships while navigating) and calculated the operational benefits of using a dispatching efford to coordinate the canal instead of respecting its arrival order.

Abstract:

Föreliggande avhandlings centrala syfte är att undersöka säkerhetskultur ombord i fartyg vilka trafikerar Östersjön. Genomgående för fartyg i Östersjöfart är täta hamnanlöp, kustnära resor, trafik i tätt trafikerade områden samt små besättningar. Tidigare forskning antyder att det kan finnas ett systemfel i sjöfarten. Charles Perrow beskriver, till exempel, sjöfarten som ett felskapande system och menar att orsaken till detta är hur sjöfarten bedrivs. James Reason menar att värdering, attityd, kompetens och beteendemönster är fyra viktiga parametrar som definierar en säkerhetskultur. Sjöfartens säkerhetsstyrningssystem, International Safety Management Code (ISM) syftar till att en proaktiv och utvecklande säkerhetskultur skapas och upprätthålls inom sjöfarten. Resultaten av den här studien visar att sjöfarten saknar en framförhållning, ”failure of foresight”, där det proaktiva arbetssättet syftar till att incidenter och olyckor kan förutses. Studien har ett etnografiskt perspektiv vilket syftar till att skapa en så fullödig beskrivning över den kultur som studeras. Totalt ingår elva olika fartyg i studien, där besöken ombord varierat från någon timme till ett par dagar. Insamlad data har via en egenutvecklad analysmodell bearbetats för att försöka förklara säkerhetskulturen. I fokus i analysmodellen står hur information, feedback, ansvar, samarbete, uppföljning samt utveckling hanteras. Studien visar att det finns behov av att diskutera och förändra säkerhetskulturen i sjöfarten, både i stort som enskilt i fartygen. Det finns ett behov av vidare studier av hur säkerhetskulturen kan förbättras, samt ett behov av riktade utbildningsinsatser inom systemtänkande, organisationsteori och säkerhetskultur.
The main purpose of this thesis is to explore the safety culture onboard vessels trading in the Baltic Sea. The common denominator for vessels trading in the Baltic Sea is frequent port visits, coastal voyages, voyages in dense trafficked areas and small crews. Earlier research shows that there may be a system fault in the shipping industry. Charles Perrow describes the maritime industry as an error inducing system. He means that the cause for that is the way shipping is carried out. In a safety culture values, attitudes, competence and behavioral patterns are four important factors that define the safety culture. The maritime safety management system, International Safety Management Code (ISM) aims towards a proactive and evolutionally safety culture in the shipping industry. The results show that shipping today lacks a foresight, “failure of foresight”, where the proactive way of work leads to incidents and accidents being anticipated. This study has an ethnographic perspective, which aims to create a thick and substantial description of the culture that is being studied. Totally a number of eleven vessels participated in the study. The visits onboard reach from a couple of hours up to a few days. Collected data has been analysed through a self-developed model in an ambition to try to explain the safety culture. The model focuses on how information, feedback, responsibility, co-operation, follow-up and development are being handled. The study reveals that there is a need to discuss and change the safety culture in the shipping industry, in large as on the single vessel. As well as a need for further studies of how the safety culture can be improved and a need for education aimed towards system thinking, organizational theory and safety culture.

Abstract:

La presente investigación tiene como objetivo analizar el impacto en la gestión logística de importación de las MYPES del sector textil bajo la aduana marítima del Callao durante los años 2012 al 2019. La influencia de los procedimientos aduaneros, costos logísticos, pago de derecho de importación y la implementación de sistemas de tecnología de la información son puntos clave a analizar dentro de una micro y pequeña empresa. Se detallará los antecedentes, teorías y conceptos que permitirán tener un panorama más amplio del sector a investigar. Las fuentes para investigar señalan que la gestión logística en el país es deficiente ya que la evaluación del IDL analizada en el año 2018, indicó que el Perú se encuentra como uno de los países con menor puntuación. Esto refleja que la cadena de suministros no desempeña una correcta función respecto a la demanda de servicios logísticos. Mediante este análisis, nace la intención de poder ahondar los problemas logísticos que mantienen las empresas en el Perú y su evolución a través de los años. Se planteará una problemática que cuestiona cuales han sido los factores que han influido en la gestión logística de importación de las empresas MYPES del sector textil en base a las investigaciones previas donde asocian la existencia de un problema en la gestión logística de importación durante la última década la cual hasta el momento no cuenta con mejoras.
The present research aims to analyze the impact on the import logistics management of small entreprises of the textile sector under the Callao maritime customs during the years 2012 to 2019. The influence of customs procedures, logistics costs, payment of import duty and the implementation of information technology systems are key points to analyze within a micro and small business. The antecedents, theories and concepts that will allow a broader panorama of the sector to be investigated will be detailed. The sources for research indicate that logistics management in the country is deficient and that the IDL evaluation analyzed in 2018 indicated that Peru is one of the countries with the lowest score. This reflects that the supply chain does not play a correct role in relation to the demand for logistics services. Through this analysis, the intention was born to be able to deepen the logistical problems that companies in Peru have and their evolution over the years. A problem will be raised that questions what have been the factors that have influenced the import management of MYPES companies in the textile sector based on previous investigations where they associate the existence of a problem in import logistics management during the last decade with which so far has no improvements.

Abstract:

La mobilité urbaine est clairement identifiée aujourd'hui comme étant la mobilitédes personnes et des biens dans une ville. Si les passagers ont connu l'effervescencescientifique pour la planification des transports, le développement de nouveaux servicesou encore la mise en place de systèmes d'information sophistiqués, il demeure unecomposante encore trop méconnue qui est celle du transport de biens. Par ailleurs,intuitivement, les deux flux s'influencent mutuellement puisqu'ils utilisent la mêmeinfrastructure. Alors, pour une autorité organisatrice des transports, l'objectif est, à terme,de rationaliser les flux de passagers et marchandises pour réduire la congestion, lapollution et la consommation d'énergie, étapes nécessaires au développement urbaindurable. Par conséquent, les services techniques de déplacements des villes s'interrogentsur les méthodes et outils pour pouvoir intégrer ces deux types de flux lors de la prise dedécisions liées à la mobilité urbaine.Cette thèse, conduite dans le cadre du projet de recherche national ANR CGOODS quiréunit plusieurs partenaires académiques et institutionnels, se propose d'évaluer l'intérêtde la mise en oeuvre d'un système de transport urbain mixte au profit de voyageurs et dufret. Le système de transport proposé assure la distribution de marchandises à partir d'uncentre de distribution urbaine, en s'appuyant sur une ligne de transport en commun. Lesvéhicules circulant sur la ligne utilisent leur capacité résiduelle pour transporter lesmarchandises. Les marchandises sont déchargées aux arrêts de la ligne. Un système dedistribution capillaire associé à chaque arrêt assure la livraison aux destinataires finauxpar des tournées. Nous visons à définir d'un point de vue organisationnel et fonctionnelles atouts économiques, environnementaux et sociétaux de ce système ; le but est defournir un cadre méthodologique pour guider sa mise en place
An efficient and effective transport for passengers and goods is an essentialelement for cities' daily life and development. As passengers need to resort to efficienttransport solutions, allowing to reach their destinations at scheduled time, similarly,goods must be handled quickly to avoid creating excessive stocks and to minimizewarehouses size and related operating costs. As urban space is a limited resource, it iscommonly argued that passengers and goods flows inter-act each other strongly.Considering the fact that both flows are growing and growing in urban environment(European Commission, 2007) the global level of urban accessibility decreases.According to this trend, congestion problems occur and as a result the travel timeincreases for all.Cities need new scenarios to reverse this trend. Facing this challenge, ourresearch aims at defining a model which will constitute a first framework to plan and tocontrol both passengers and goods flows in the urban environment. It focuses on thesharing concept, which means to make a joint use of transport resources, betweenpassengers and goods flows. Driving under the national research project ANR CGOODS(City Goods Operation Optimization using Decision support System) this study assessesthe interest of implementing an shared urban transport system. The proposed transportsystem ensures the supply of goods in a medium-sized town, from an urban distributioncenter, based on a transit line that carries passengers. Vehicles running on the line usetheir residual capacity to transport goods. The goods are unloaded by the stops of the line.An capillary distribution system associated with each stop ensures goods deliveries tofinal destinations. We aim to define the economic, environmental and societal impacts ofthis system, the purpose being to provide a methodological framework to guide itsimplementation

Abstract:

La politique actuelle des transports répond à la nécessité de trouver une solution logistique, compétitive et durable à l’augmentation des échanges internationaux à travers l’élaboration du concept d’autoroutes de la mer. L’objectif de report modal associé aux autoroutes de la mer ne se retrouve pas au sein des Etats tiers méditerranéens. Dans cette région, les autoroutes de la mer se caractérisent par le développement d’infrastructures portuaires qui permettront d’aspirer les flux de marchandises de certains ports du Nord de l’Europe largement saturés. L’innovation réside dans l’approche systémique adoptée. La chaîne de transport est envisagée dans sa globalité pour un transport porte à porte. Compte tenu du contexte concurrentiel des transports qui a eu pour effet d’entraîner l’arrêt d’un certain nombre de lignes maritimes régulières, on peut être conduit à s’interroger sur les conditions de viabilité de ce concept. Face à cette situation, a priori, quelque peu défavorable, nous avons recherché, au cours de cette étude, quels sont les leviers juridiques qui pérennisent le concept. D’une part, nous avons insisté sur l’élaboration d’un régime juridique des entreprises de transport multimodal. D’autre part, l’étude montre que la viabilité économique du concept est subordonnée à l’existence d’instruments financiers incitatifs. Enfin, la promotion de transports durables tels que les services des autoroutes de la mer, sous la forme juridique d’une allégation environnementale, permettrait utilement d’informer les chargeurs et les professionnels sur les avantages énergétiques propres à ce concept, ce qui ne pourrait que lui être particulièrement favorable
The current transport policy fulfills the need for a logistical, competitive and sustainable solution to the growth of international trade through the implementation of the Motorways of the sea concept. The Motorways of the sea aim to shift road freight to maritime traffic, and are characterized by their regularity, their frequency and integration into logistics chain. However, the modal shift goal linked to the Motorways of the sea is not the same within the third-Mediterranean States. In this region, the Motorways of the sea are determined by the development of port infrastructures which will allow to draw in the flow of freight from certain saturated northern european ports.The innovation rests in the adoption of a systemic approach. The economical reason driving the euro-mediterranean transport policies as well as the diagnosis of the mediterranean transport system, demonstrate the challenge faced by the mediterranean Motorways of the sea is considerable. Considering the competitive context surrounding the transport sector together with the difficulty to integrate the motorways of the sea within the transports chain, we intend to question the viability of this concept. In view of the situation slightly unfavorable, we have researched, in this study, what are the legal means perpetuating this concept in order to allow its integration to the competitive network of transports. On one hand, we have focused on the implementation of a legal system for a binding to international treaties.On the other hand, the study evidence that the economical viability of this concept is related to the existence of financial incentives which application, sometimes, requires financial engineering to obtain the funds potentially available. Finally, the motorways of the sea could benefit from a legal environmental information, like goods and services, informing loaders, and other professional on the advantages of this concept

Abstract:

Mestrado em Gestão de Sistemas de Informação
A integração logística é uma condição determinante para o desenvolvimento do transporte maritímo-portuário. O presente trabalho de investigação propõe-se demonstrar que essa integração passa por adoptar uma estratégia digital e que a tecnologia emergente de Web Services constitui já uma boa aproximação. O transporte marítimo-portuário caracteriza-se pela multiplicidade de nós, de actores, concorrentes com diferentes papéis, por atravessar fronteiras, e por ser suportado por relações comerciais individualizadas entre pares de parceiros, pelo que, para a caracterização deste sistema e para encontrar as respostas às questões em investigação, se optou por efectuar uma triangulação de várias fontes de informação. A metodologia usada consiste na análise de alguns estudos europeus, que oferecem o enquadramento na EU, sendo aplicado o estudo de casos a algumas empresas de um porto português e a teoria de grafos para a análise da rede marítima do porto. É ainda efectuado um Benchmarking com o transporte aéreo, para comparar, nos aspectos em análise, as opções tomadas. Finalmente é verificado, se existe oferta do lado dos fornecedores de soluções TI. Atingir uma integração logística, passa por garantir a interoperabilidade ao longo da cadeia logística, visando a reutilização da informação através de infra-estruturas TI flexíveis e partilhadas. Sistemas de EAI ou Enterprise Application Integration, bem desenhados e implementados, permitem que as organizações respondam agilmente, e em tempo útil, às necessidades de mudança e inovação. Os Web Services baseados em XML, normas abertas e tecnologia Internet, prometem potenciar estes requisitos do negócio. Com base nos resultados obtidos são feitas algumas sugestões e proposto um modelo conceptual que visa fomentar a interoperabilidade das TI entre os diferentes actores e possibilitar uma efectiva gestão do conhecimento. Face à complexidade e interesse do tema, são ainda sugeridos futuros trabalhos.
This research has the goals of identifying if the emerging Web Services technology could be a good approach for a strategy in the digital arena of the maritime-harbour business and also to suggest a conceptual model for that strategy. In order to pursue the goals in this industry, collaboration and integration enhancement is required, aiming information reuse throughout sharing flexible IT infrastructures. Supply-chain interoperability is becoming an essential requisite to accomplish. EAI systems or Enterprise Application Integration systems, well designed and implemented, allow the organizations to address both business changes and innovation needs. The XML based Web Services, open rules and Internet technology, promise to enable these business requirements. This business has many players with different roles, and goes over borders, and therefore, in order to characterize the system being studied and to find the right answers to the questions under research, it was chosen a triangulation approach, using different information sources. First of all, using some European final reports, which convey the EU situation. Secondly, the case study research is applied to some companies working in a Portuguese harbor, as well as the graph theory for the maritime net analysis. Thirdly, a benchmarking with the air transport is also made in order to identify the chosen options under the different criteria being analyzed. Finally, it is checked which solutions are available from the IT market suppliers. Based on the results found, some recommendations are made and a conceptual model is proposed in order to boost the IT interoperability among the different players, enabling an effective global knowledge management. Given the complexity of this subject, future work is also suggested.

Abstract:

Measured in volume approximately 80 % of world trade is carried at sea and with just as many different actors the shipping industry acts close to a perfect market. The highly volatile nature of the industry with unexpected market fluctuations is the basis for the major decisions shipping companies are making. Especially the fleet size and mix problem in a strategic setting involving fleet changes during several planning periods as a company growth policy. This decision is therefore highly dependent on correct timing for those who want to succeed and an introduction to the shipping industry is given to state these properties. In this thesis various optimization models solving the fleet size and mix problem are presented where the best suited model structure related to the topic is chosen. This model is of deterministic nature, meaning that all input values are known, and based upon predefined routes. The decision regarding the fleet composition during several planning periods is aiming at determining an optimal fleet for a given market. The validity of the results solely relies on input data, which is highly uncertain into an unknown future. The predictions need to coincide with the real life development in order for the results to maintain its validity.Two different trades are used as cases, solved with the models presented. Some input parameters are changed and the differences are investigated. The main findings imply that only relative small changes of the input parameters resulted in very different decisions. The related loss of making the wrong decision is observed in the region of 100 – 200 million USD during three years. This large loss potential and the uncertainty related to the input parameters leads to a need for a method minimizing these effects. An approach is developed to treat uncertainties minimizing the losses by finding a robust fleet capable of handling a large set of generated future scenarios, called the “Scenario Algorithm”. The approach is divided into three main steps; the scenario generating step where development are based on historical fluctuations, a deterministic solution with the given scenario as basis and finally storing of all the solutions with a statistical analysis of the output. The algorithm is used on the two cases with two different scenario generating approaches, based on an exponential- and a continuous uniform distribution. The fleet size and mix decisions which appeared with the highest frequency were chosen, and gave a consistent estimate based on risk aversion decreasing the potential of making losses.The approaches presented in this thesis is not meant to give a correct answer on how the future will be, but help the decisions makers reduce the uncertainty connected to the strategic decision. The deterministic model give valuable information with a given scenario as input, but the model is only capable of evaluate the scenarios individually. The result found by the scenario algorithm evaluating scenarios collectively is therefore of higher value since it provide a more robust solution.

Abstract:

The internationalisation of investments and the globalisation of the markets have created a high level of competition among manufacturing and services companies which has transcended the competition among nations. In this environment, quality information and exact timing are the sole answers for generating comparative and competitive advantages with respect to other manufacturers and providers. Inspired by these challenges, Latin American countries have searched for ways to increase and diversify their exports in order to heighten their trade balance surpluses. This, in turn, helps them to overcome their debt problems and gain access to a better quality of life. With these criteria in mind, these countries have begun to join the economic aperture and globalisation processes. United by their common ethnic heritage, they are driven by the growing need to co-ordinate national and regional decisions in order to achieve a harmonic community development. The efficiency principle imposed by the present international trade scenario requires extreme attention to detail in the administration of production costs and in placing products on the market. Because a product's success is highly sensitive to cost and distribution methods, maritime transport and its associated systems require very specific management techniques. Those management techniques must take into account that as transport is a service it gives added value to the cargo. Thus, the management model, costs involved, planning processes, and area policies are topics of vital importance for achieving these nations' development objectives. The design of specific policies, both operational as well as for development (investments), should comply with certain minimum conditions. The resulting policies should satisfy integrally and harmoniously the requirements the State establishes in its general National Development Strategy. This strategy considers factors of monetary and trade uncertainty. States must be particularly careful to interpret changes, tendencies, circumstances and difficulties which emerge in the international markets they serve, correctly. Therefore, the purpose of this study is to analyse the existing maritime transport logistic system in Chile, beginning with the history of ports and economic development. Subsequently, this study will analyse all relevant information related to logistics and the lessons learnt during the process of modernization. For analytical purposes, the study establishes an evaluation area which has been represented by a "graph" built up from nodes and links.These symbolise the complex network of port systems, hinterlands, roads, railways and coastal shipping. Likewise, the links and nodes have direction, intensity and values that the study intends to describe and evaluate. Moreover, hinterlands are not as exclusive as they were before. Consequently, most of the port systems face a very competitive market in offering services for international hinterlands/foreland. Therefore, this thesis will conclude that at least some Latin American countries establish land bridges between them. There have been some studies about the land bridges, "inter-oceanic corridors" or "integration corridors" options in South America.The Pacific Ocean Basin and the APEC countries represent a huge market for those Atlantic countries which have products to export and import from that vast area of the globe. The existence of the main industrial site of South America running from the Atlantic side of South America to the Pacific Coast, which forms an "Industrial Banana", is the foundation of a massive demand to and from both coasts. The study evaluated the logistics system through different criteria, such as logistics, physical capacities, and economic, social, environmental and political considerations. Having established these criteria, the researcher can better evaluate the relevant parameters and variables to consider in the design of the parametric model.
La internacionalizacion de las inversiones y la globalizacion de los mercados, han creado un alto nivel de competitividad entre los proveedores de manufactura o de servicios, lo que trasciende a la competitividad entre las naciones. En este escenario, la informacion de calidad y respuesta en tiempo real son la respuesta para generar ventajas comparativas y competitivas respecto de otros productores y proveedores. Inspirados en estos cambios, los paises Latinoamericanos han buscado formas como aumentar y diversificar sus exportaciones, con el proposito de incrementar sus balanzas comerciales. Esto les ayuda a sobrellevar sus problemas de deuda, accediendo a mejor calidad de vida. Con estos criterios en mente, los paises de la Region han accedido a los procesos de apertura economica y globalizacion de los mercados. Unidos por la herencia etnica comun, ven una creciente necesidad por la coordinacion de sus decisiones nacionales y regionales, de manera de alcanzar el desarrollo comun de manera harmonica. Los principios de eficiencia impuestos por el presente esquema de comercio internacional, requiren de una atencion especial en la gestion de los costos de produccion y en la colocacion de los productos en los mercados. Considerando que el exito del producto es sensible a su costo, los sistemas de distribucion y logistica requiren de tecnicas especificas de gestion. Por ello, los modelos de gestion, costos, procesos de planificacion y politicas sectoriales son de vital importancia para alcanzar los objetivos nacionales de desarrollo. El diseno de politicas sectoriales, tanto operacionales como de desarrollo (inversiones), deberian cumplir con los minimas condiciones para lograr su objetivo pais. Las politicas resultantes debieran satisfacer de manera integral y harmonica, los requirimientos que el Estado ha establecido en su Estrategia Nacional de Desarrollo. Dicha estrategia debe incluir las incertidumbres monetarias y de commercio. Los Estados deben ser particularmente cuidadosos para interpretar correctamente los cambios, tendencias, circunstancias y dificultades que emergen de los mercados internacionales que ellos sirven. Por lo indicado anteriormente, el proposito de esta tesis es analizar el sistema de logistica maritima en Chile, comenzando con la historia de sus puertos y desarrollo economico, posteriormente el analisis de la informacion relevante a logistica y las lecciones aprendidas durante el proceso de modernizacion economica. Con propositos analiticos, el estudio determino una zona fisica de evaluacion que esta representada por la "teoria de grafos". Esta simboliza la compleja red de puertos, hinterlands, caminos, ferrovias y transporte maritimo costero. Los nodos y sus enlaces tienen direccion, intensidad y valores que el estudio pretende evaluar y dimensionar. Mas aun, en la actualidad el hinterland de los puertos ha dejado de ser exclusivo, consecuentemente, los sistemas portuarios enfrentan una agresiva competencia para ofertar servicios a sus hinterland/foreland, por lo cual algunos paises latinoamericanos construyeron "puentes terrestres" entre ellos, el estudio indica algunas opciones de "puentes terrestres", "corredores inter-oceanicos" o "corredores de integracion" identificados en America del Sur. La cuenca del Pacifico y los paises APEC representan un mercado enorme para los paises de la costa Atlantica. La existencia de la principal area industrial de Sudamerica se configura entre el Atlantico y Pacifico, forma lo que el autor denomina como la "Banana Industrial", lo que origina una enorme demanda en los dos sentidos. El estudio evalua los sistemas desde diferentes criterios, tales como: sus capacidades fisicas y logisticas, sus consideraciones economicas, politicas, sociales, y medio ambientales. Una vez establesidos los criterios, el investigador puede identificar y evaluar de mejor forma los parametros y variables a considerar en el diseno del "modelo parametrico".

Abstract:

The following study that is the regulatory settings for a port operator has been conducted with the intention to comprehend and highlight the different regulatory settings appropriate for the sea ports in order to ensure safe, reliable and efficient trade and transportations practices at sea ports. The area of focus of this research work was towards the Baltic Sea region ports where the researcher focused on the evaluating the regulatory settings for four different ports in order to compare and contrast each other with the intention to validate every port follows certain regulations. The researcher with the support of secondary quantitative study with the deductive research approach has intended to answer the problem of this research work. The findings of this study have suggested that different regulations on the basis of the international conventions are strongly considered by the range of ports especially Port of Gdansk, Port of Helsinki, Port of Tallinn and Rostock ports that have examined. Nevertheless, there were also some regulations which not all the ports were following thereby confirming all the ports follow certain regulations which are in accordance with their changing scenarios.

A dissertação trata-se de um estudo de viabilidade da exportação do couro de peixe sob determinados índices de aproveitamento - Peso e Volume, e seu desempenho logístico. Faz-se então, uma análise comparativa do transporte marítimo internacional com o transporte aéreo e suas atribuições mais relevantes no custo final da mercadoria. O estudo constatou o desempenho logístico de alguns atributos responsáveis pela rentabilidade da atividade, concentrando-se a priore no aproveitamento do subproduto do peixe - resíduos beneficiados que geram o couro da tilápia, e sua exportação através de curtumes, como exemplo o "Curtume Fish Skin" ainda um projeto de empresa. No decorrer da pesquisa, conclui-se que na Europa estão as melhores oportunidades de negócio e que, os europeus seriam os principais consumidores do produto - couro de tilápia, como matéria prima de artefatos exclusivos, exemplos bolsas, calçados, acessórios e vestuário, posto que, o aquecimento do mercado europeu, principalmente após o surgimento do Euro, é fato. A Europa continua sendo o grande centro referencial da moda para o mundo e, o poder aquisitivo diferenciado diferenciado advindo da evolução econômica do mercado europeu, é uma realidade inconteste nas empresas e no cotidiano dos cidadões. Por sua beleza exótica, resistência e textura e, sendo ainda, matéria prima de baixo custo, trazendo valor agregado, não predatória, com projetos e ações contínuas de não agressão ao meio ambiente e de proteção a espécie, o couro de tilápia, apresenta-se com ótima capacidade de prosperidade, neste e em outros mercados. Com base em uma pesquisa dedutiva, exploratória, conclusiva descritiva e análise bibliográfico. Conclui-se nesta dissertação, que além do diferencial da matéria prima exótica, de baixo custo e com valor agregado, os percentuais obtidos na avaliação dos índices de aproveitamento de peso e volume, no custo da logística do transporte para exportação do couro da tilápia, permitem após melhorias baseadas no resultado dos índices, ao produto final, um preço competitivo, fator este, decisivo para a empresa manter-se no mercado internacional com segurança e rentabilidade a médio e longo prazo. The dissertation studies the fish leather exportation feasibility under certain rates of advantage - Weight and Volume, and its logistic performance. It had been done a comparative analyze of the international seaside transport and air transport and their attribute more relevant in the final merchandise cost. The study was there on the logistic performance of some attributes responsible by the activity profitability, it concentrateditself first in the advantage of the sub product of fish - benefit residues that create the tilapia`s leather, and its exportation through the tanneries, such as the " Curtume Fish Skin" yet a company project. In the develop of the research, it was conclud that in Europe are the best business opportunities and that the European people would be the mainly consumers of this product - tilapia`s leather, as raw material to exclusive product, for exemple: bags, shoes, accessories and clothing, saying that the European market warming was mainly after Euro creation, it is fact. Europe continues being a big fashion referential center to the world and the different purchasing power that comes from the economic evolution of the European Market is a reality in the citizen and companies everyday life. For its exotic beauty, durability, with projects and continue actions to not attack the environment and the species protection, the tilapia`s leather shows itself as an excellent prosperity capacity, in this an other markets. We can conclude with this dissertation that beyond the exotic raw material the low cost and the lodger value, the percentage obtained in the evaluation of the volume and weight rate, they show tha the bussiness is very safe and a medium and long time economic.

Abstract:

A gestão das ameaças e dos riscos nas empresas tem se dedicado a estudar estes problemas, pelo viés de mercado, com o intuito de torná-las mais preparadas para enfrentar estes desafios. Nesse sentido, uma série de instrumentos de análise diagnosticaram que as ameaças e os riscos fazem parte da natureza das relações empresariais. Dentre as inúmeras relações que uma empresa estabelece para atingir os seus objetivos, destacam-se as que estão inseridas em um sistema denominado “cadeia de suprimentos” que, em decorrência do processo de globalização tornou-se internacionalizada. As empresas, ao prolongarem suas cadeias de suprimentos “além fronteiras”, estão submetidas, às influências do ambiente econômico, geopolítico, social e histórico. Nesses ambientes, o ano de 2001 originou uma série de estudos de gestão de risco que identificaram, nas ameaças externas ou exógenas, isto é, as que estão fora do viés de mercado, a possibilidade de tornar a cadeia de suprimentos internacional insegura. Tais ameaças se configuram em ações da natureza e ações praticadas pelo ser humano, por meio de atos criminosos, como, o terrorismo, o tráfico, o contrabando e a pirataria marítima Além das empresas, os países criaram regimes internacionais que buscaram proteger as cadeias de suprimentos, principalmente, em seu sistema de transporte, destacando-se o modo chamado “marítimo”, em razão da sua intensa utilização para transportar cargas. O presente estudo tem como objetivo propor um protocolo de gestão de risco para o transporte marítimo de cargas “less than container load”, para tornar a cadeia de suprimentos internacional mais segura. A metodologia utilizada nesta pesquisa, foi descritiva e documental, já que descreveu o processo de operacionalização e baseou-se na análise dos documentos, utilizados na gestão do transporte marítimo “less than container load”. Conclui-se, assim, que o operador de transporte multimodal, como responsável por operacionalizar uma forma de transportar cargas, a qual torna a cadeia de suprimentos insegura, tem condições e, principalmente, o dever de juntar-se aos outros atores, em prol do aumento da segurança do sistema.
The management of threats and risks in the company has been dedicated to study these problems by market bias in order to make them better prepared to face these challenges. In this regard a number of analytical tools diagnosed threats and risks as part of the business relations. Among the many relationships that a company established to achieve their goals, we highlight those that are embedded in a system called the supply chain, which as a result of the globalization process has become internationalized. Companies to extend their supply chains "across borders", are subject to the influences of economic, geopolitical, social and historical environment. In these environments, the year 2001 led to a series of risk management studies that have identified the external or exogenous threats, those outside the market bias, the possibility of making the chain of uncertain international supplies. Such threats are configured shares of nature and actions taken by humans, by means of criminal acts as terrorism, trafficking, smuggling and maritime piracy In addition to companies, countries have created international regimes that sought to protect supply chains, especially in its transport system, highlighting the called maritime, because of their heavy use to transport cargo. The thesis aims to propose a risk management protocol for the shipping cargo "less than container load" to make the international supply chain more secure. The methodology used was based on descriptive type and documentary because described the operational process and analized documents used in the management of shipping “less than container load”, In conclusion, the multimodal transport operator who is responsible for operating a means of transporting cargo , which makes the supply chain insecure supplies, has conditions , and especially the obligation to join the other actors , in favor of the increase system security.

Abstract:

Il trasporto marittimo è una delle modalità più utilizzate soprattutto per la movimentazione di grandi volumi di prodotti tra i continenti in quanto è a basso costo, sicuro e meno inquinante rispetto ad altri mezzi di movimentazione. Ai giorni nostri è responsabile di circa l’80% del commercio globale (in volume di carichi trasportati). Il settore del trasporto marittimo ha avuto una lunga tradizione di pianificazione manuale effettuata da progettisti esperti.  L’obiettivo principale di questa trattazione è stato quello di implementare un modello matematico lineare (MILP, Mixed-Integer Linear Programming Model) per l’ottimizzazione delle rotte marittime nell’ambito del mercato orto-frutticolo che si sviluppa nel bacino del Mediterraneo (problema di Ship-Scheduling). Il modello fornito in questa trattazione è un valido strumento di supporto alle decisioni che può utilizzare uno spedizioniere nell’ambito della pianificazione delle rotte marittime della flotta di navi in suo possesso. Consente di determinare l’insieme delle rotte ottimali che devono essere svolte da un insieme di vettori al fine di massimizzare il profitto complessivo dello spedizioniere, generato nell’arco di tempo considerato. Inoltre, permette di ottenere, per ogni nave considerata, la ripartizione ottimale della merce (carico ottimale).

Esta tese tem como objetivo apresentar um modelo que analise os efeitos sistêmicos da política de colaboração entre indústrias manufatureiras que utilizam o transporte marítimo para a exportação, levando em consideração os principais parâmetros estratégicos e operacionais envolvidos nessa operação, sendo, portanto, desenvolvida através de duas frentes: uma teórica e outra computacional. Na frente teórica foi efetuada uma pesquisa bibliográfica sobre a era da Logística Colaborativa e a Gestão do Transporte Colaborativo, voltados à exportação de produtos manufaturados. Ao mesmo tempo foram realizadas entrevistas com empresários e especialistas do ramo de modo a validar a proposta de estudo, além de obter dados para inserção no modelo. Posteriormente, definindo a Simulação como técnica para modelagem do problema, foi realizado um estudo sobre os métodos Agent Based Modeling and Simulation e System Dynamics. Após análises e comparações, optou-se pelo método System Dynamics para dar continuidade à modelagem. Em relação à frente computacional, o modelo contribuiu para a análise dos efeitos sistêmicos da política de colaboração entre indústrias manufatureiras, as quais se unindo fortalecem o poder de barganha sobre os armadores marítimos, influenciando na redução do preço de frete marítimo. Este trabalho contribuiu para o entendimento da importância de se adotar uma abordagem interdisciplinar para lidar com os problemas do transporte marítimo, sendo por fim apresentados os benefícios do transporte colaborativo marítimo identificados com a realização do mesmo.

This research intends to get opinions, knowledge and expectations concerning to the professionals involved with export operations at specialized agribusiness port terminals, at Port of Santos - Brazil. Four main dimensions were studied: the characteristics of Dry Bulk Carrier Ships; the infrastructure of roads, railroads as well as the port; the expected influences brought by "ships of future" over export contracts; and the change needs forced by concurrential enviroment. The analysis is a part of agribusiness sector, specially the commodities soya beam and sugar. The understanding of port changes, market changes, as well as Naval Industry trends, can make the difference between those to be competitive or not, in a global market. To know in advance the answers for the needs of change, in what dimension to deal with and to act, become strategic factors to achieve the competitive advantage, comparing with other competitors port terminals. Many articles concerning the modernization and privatization of Port of Santos, can found in magazines and newspapers, but a few information have been published in books and scientific papers. The knowledge about the trends related to port enviroment, Naval Industry and maritime freight market were used to elaborate the questionnaire for the research, in order to investigate the opinion, the knowledge, and the professional's expectations. The findings, for the sample studied, indicates a good level of organizational changes. Therefore, the technological, regulatory, and market pressures over port terminals contributes to grow an isomorphism in organizational structures. This question could be investigated, on further studies. This theme is a wide-ranging in Management, as well as the field of Logistics. The present investigation brings more knowledge, and stimulates new scientific contributions in the field.
Este trabalho tem por objetivo pesquisar as opini??es, o conhecimento e as expectativas dos profissionais que participam das opera????es de exporta????o de gran??is agr??colas, por meio do Porto de Santos, sobre quatro dimens??es b??sicas: as caracter??sticas dos navios graneleiros; as infra-estruturas rodovi??ria, ferrovi??ria e portu??ria; o impacto do navio do futuro nos lotes vendidos e embarcados; e as necessidades de mudan??as provocadas pelo ambiente concorrencial. O setor analisado ?? o agro neg??cio, especialmente soja em gr??os e a????car. Entender as transforma????es portu??rias, do mercado, bem como os impactos que as tend??ncias da Ind??stria Naval trar??o aos terminais especializados, pode fazer a diferen??a entre ser competitivo globalmente, ou inviabilizar-se perante o mercado internacional. Conhecer previamente as necessidades de mudan??as, saber as respostas, e em que dimens??o agir, tornam-se fatores estrat??gicos para a vantagem competitiva, perante os terminais portu??rios concorrentes. Muito se fala a respeito do Porto de Santos, e de seu Programa de Arrendamentos e Parcerias, especialmente nos ??ltimos tr??s anos, em que o porto tem quebrado recordes anuais seguidos de movimenta????o de cargas. A maioria do material divulgado diz respeito a estat??sticas, artigos de revistas, de jornais de neg??cios, e de jornais de grande circula????o. Poucos livros e artigos cient??ficos tratam do tema. Por meio de pesquisa bibliogr??fica, procurou-se conhecer as mudan??as que t??m ocorrido, e as futuras tend??ncias, em tr??s principais esferas: o ambiente portu??rio, a Ind??stria Naval, e o mercado de fretes mar??timos. Essas informa????es serviram de base para a elabora????o do question??rio de pesquisa, com a finalidade de aferir a opini??o, o conhecimento, e as expectativas dos profissionais a respeito do assunto. Os resultados apontaram, para a amostra de sujeitos pesquisados, uma homogeneidade entre as opini??es, um bom grau de conhecimento sobre o tema, e uma boa sensibilidade sobre as necessidades de mudan??as organizacionais. As press??es tecnol??gicas, regulat??rias e comerciais, s??o fatores que contribuem para o direcionamento rumo ao isomorfismo das estruturas organizacionais dos terminais portu??rios analisados. Tal tema merece ser investigado em futuras pesquisas. O assunto desta pesquisa ?? abrangente, assim como o campo de conhecimento de Gest??o de Opera????es e Log??stica, e n??o se encerra com a realiza????o da presente pesquisa. Ela apenas amplia o conhecimento, instigando novas, e necess??rias, contribui????es acad??micas nesse campo.

Abstract:

L'espace portuaire industriel et logistique français est largement héritier de la période des Trente Glorieuses. Celle-ci a vu naître les zones industrialo-portuaires, initiées, gérées, exploitées par l'État au travers d'établissements dédiés, les ports autonomes. Ce système est déstabilisé par la globalisation de l'industrie maritime et la libéralisation du secteur portuaire, entamées dans les années 1980. Ces deux tendances participent à la diffusion à l'échelle mondiale du modèle de gestion dit landlord port, selon lequel l'exploitation portuaire est confiée à des opérateurs privés. Les entités publiques gestionnaires de ports (ou autorités portuaires) voient quant à elles leur champ d'action recentré autour de l'aménagement et de la gestion de leur domaine. En France, la réforme portuaire de 2008 sanctionne cette transition; les grands ports maritimes se substituent aux ports autonomes. Cette thèse appréhende les effets de ces mutations sur la production et la gestion de l'espace portuaire, saisies à partir des pratiques des autorités portuaires des grands ports français. Tout en restant placées sous le contrôle de l'État, celles-ci voient leur autonomie et leurs compétences s'élargir. Il en découle un déploiement spatial et une diversification de leurs interventions, traditionnellement centrées sur la construction et l’entretien des infrastructures portuaires. La trajectoire de l'aménagement portuaire fait écho à celle d'autres espaces infrastructurels (ferroviaires, aéroportuaires). Elle met en lumière les continuités et les ruptures qui marquent l'action de l'État au cours des dernières décennies dans l'aménagement du territoire
Legacies from the Glorious Thirty still contribute to shape French industrial and logistic port spaces to a large extent, from morphological, economic and institutional point of views. During this period, maritime industrial development areas have been created. There were managed and operated by the state, through dedicated public bodies named ports autonomes. The globalization of the maritime industry and the liberalization of the port sector which started during the 1980s have unsettled this system. These two tendencies have led to the adoption of the "landlord port" management model by main ports worldwide. In this model, port operation is conducted by private enterprises while public port management entities (or port authorities) focus on planning, developing and managing land in the port area. In France, this transition occurred with the port reform of 2008, through which ports autonomes became grands ports maritimes. This PhD research aims at understanding the effects of these changes on port land planning, development and management, through the analysis of the practices of the port authorities of French main seaports. The latter are still under the control of the state, but their autonomy and their competencies have been enlarged. While they traditionally focus on the construction and the maintaining of port infrastructures, their interventions tend to spread in space and to diversify. The trajectory of port space management and development echoes that of other infrastructural spaces (rail or airport spaces). This work contributes to shed light on the continuities and ruptures of state intervention in territorial planning and development in the last decades

The goal of this study is to show how the resource?s rationalization can improve the operational results of one maritime transport company. The tanker maket follows a world tendency on the hiring price of charter. It makes the process of costs reducing through the optimization of fuel and diesel or/and through the performance?s control of time, velocity and operational disponibility a mandatory factor. The control of the consume of fuel and diesel is a way to reduce the discounts on the ships earns. The losses can be caused by technical problems on the MCP's (Main Combustion Engine), MCA's (Auxiliary Combustion Engine) and auxiliary machinery of the ships, or by the necessity of revaluation on the contractual price of loading and unloading products on shipping terminals and also by the climate changes in the Brazilian coastline, which causes some different conditions of velocity and time trips.
Atrav?s deste trabalho pretende-se apresentar como a racionaliza??o de recursos pode contribuir para melhorar o resultado operacional de uma empresa de servi?o de transporte mar?timo. O mercado de afretamento de navios petroleiros segue uma tend?ncia mundial na contrata??o do pre?o do frete, tornando importante o processo de redu??o de custos atrav?s da otimiza??o de ?leo combust?vel e ?leo diesel, e controle das performances operacionais: tempo, velocidade e disponibilidade operacional. Uma das formas de reduzir os descontos na receita dos navios ? o controle do consumo de ?leo combust?vel e ?leo diesel. Sejam eles provocados por problemas t?cnicos nos MCP?s (Motor de Combust?o Principal), MCA?s (Motor Auxiliar de Combust?o) e M?quinas Auxiliares dos navios, ou at? mesmo pela necessidade de reavalia??o de taxas contratuais de bombeio de carga e descarga de produtos nos terminais, e velocidade/tempo de viagem em alguns trechos do litoral brasileiro, devido ?s mudan?as clim?ticas e geogr?ficas.

Abstract:

Now a day, petroleum companies are looking for a way to calculate the best economic and time consuming alternative to move a group of ships between platforms, refineries and consuming centers. In the following research is introduced a solution to this problem through a system which optimize the main variables involved. Variables such as scheduling and road have been taken into account. The variable scheduling defines the road that each ship must follow. Meanwhile, the optimization of the route is based on traveling time between each points, uploaded and downloaded time, storing capacity at each point, etc. The following system has been tested in two real cases showing a good performance.

Hoje em dia, as empresas petroleiras enfrentam o desafio de conhecer qual é a melhor forma de movimentar uma frota de navios cargueiros sem que isso signifique um aumento de custo, entre outras. Neste trabalho será apresentada uma solução para este, mediante o desenvolvimento de um sistema que permita calcular as rotas para transporte de petróleo bruto de plataformas marítimas a refinarias, bem como transporte dos derivados do petróleo de refinarias a centros consumidores. Para a solução do sistema, foi realizado um scheduling no qual determina-se a rota que cada navio deve realizar para que o petróleo sea entregue, buscando a rota que conduza ao melhor caminho, sendo considerado o tempo de deslocamento, carga e descarga do produto, além do limite de armazenamento de produto em cada plataforma, entre outros parâmetros.

Abstract:

Low Intensity Conflict (LIC) is a significant feature of the contemporary world and it is a particular challenge to the armed forces of many states which are involved is such conflict, or are likely to become so. This thesis is not concerned with how such difficult conflict situations arise. Rather it is concerned with how, from the point of view of the state, they may be contained and ultimately brought to a satisfactory resolution. The work is thus concerned with the practicalities of ending LIC. More specifically, the purpose of this research is to establish a framework of doctrinal and military principles applicable to the prevention and resolution of LIC. The principles of this thesis are based in numerous historical examples of LIC and six in depth case studies. These distilled principles are analysed in two central chapters, and are then applied in two latter defence force chapters so as to ensure there practicality and resilience. Numerous defence academics and military practitioners have been consulted in the production of this thesis; their contribution has further reinforced the functionality of the principles examined in this research. The research illustrates the criticality of a holistic approach to LIC. The function of this approach is to guarantee the stability of the sovereign state, by unifying civil, police, intelligence and military services. The effectiveness of the military elements must also be ensured, as military force is central to the suppression of LIC. Consequently, the research makes strategic and operational prescriptions, so as to improve the capability of defence forces that are concerned with preventing or resolving LIC.

Globalization has unleashed technological advancement which triggered change and fostered development in transportation patterns, making cross border trade easier. Consequently, the impact of export on transportation and logistics has commanded attention in recent studies. This thesis used the gravity model and cluster analysis based on 2007 and 2013 global trade cross-sectional data. Through the basic gravity model variables, logistics performance index, liner shipping connectivity index (container transport) and quality of port infrastructure index, amongst others, the study explored the role of sea transport in bilateral trade as well as the impact on the export of each industry. Moreover, the study further analyzed world shipping core countries between cluster effect and industrial relations. The major findings of this research are as follows: (1) Firstly, the overall aspects such as logistics performance, liner shipping connectivity index have high influence on exports. The quality of port infrastructure index is stronger on the inter-temporal which ultimately affects the quality of a country. Accordingly, better quality drives good progress, and conversely, poor quality hinders development and limits exports. (2) Secondly, in industry, logistics performance improvement of the secondary industry’s raw materials manufactured goods, machinery and transport equipment has a positive and more stable influence on the export of other industrial products. Subsequently, general consumer goods industry mostly adopt the international container transportation. More attention is given when the liner shipping connectivity index rises which implies that container transport is more convenient and can help to export specific products, and enhance trade. (3) Lastly, the Asian international container transportation status rose precisely due to Europe’s single core spill over into Eurasia dual core model.

Abstract:

The competitiveness of a seaport highly depends on its efficiency, especially in terms of how its logistics operations are integrated with those of other logistics chain partners. Despite the well-articulated importance of ports and terminals in integrated logistics, research on the success factors of port logistics integration remains scattered. This study aims to identify key factors in port logistics integration and how logistics integration can be improved. To identify the key factors in port logistics integration, a review of the literature is conducted to cover studies in Scopus indexed journals on logistics, supply chain and port management for the period 2000-2016. Based on the results of the literature review, a conceptual framework for port logistics integration is developed and applied to a study of logistics integration in the Iranian port sector. The Iranian port sector is chosen due to its critical role in the Iranian economy and seaborne trade, and lack of research on the port sector in this country despite its strategic location in the Middle East region. The study makes use of data collected from a survey and interviews of senior staff and managers from ports, terminal operating companies, freight forwarders, transport providers, port authority, shipping lines, customs and shippers in Iran. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are applied to the data set of 212 observations to identify and analyse the key factors in port logistics integration and their relationships. The results of EFA and CFA indicate that the logistics practice, information integration, value-added services, logistics practices, organisational activities, resource sharing and institutional support are influential to logistics integration. In addition, it has also been found that logistics integration in the Iranian port sector is subject to a number of issues and challenges relating to infrastructure, operational/ technical, Managerial/ organisational, governance and policy, and sanctions. Using Nvivo Software and data collected from 105 interviews, the results of the qualitative analysis revealed that the lack of integration and coordination between logistics chain partners, management/ organisational issues and infrastructural issues are among the most important challenges in port logistics integration. Moreover, infrastructural development, the participation of logistics partners in the port’s decision-making process, information and technology development, and integration of procedures and systems are highly recommended as measures to overcome the above challenges. Based on the findings of the quantitative and qualitative analysis, several implications, and recommendations for port management and policy makers are discussed. For example, ports need to foster close, collaborative relationships with logistics chain partners in information exchange, communication, logistics operations management, port development, and joint decision-making process. Furthermore, ports need to make effective use of existing information and communication technologies; for example, EDI, online transactions and real-time cargo tracking. Given the deficiencies in infrastructure and investment, institutional support is needed such as loans/microcredit and lease facilities. To a broader extent, port development needs to be aligned with that of rail and road transport as part of the transport and logistics system. The sector can also benefit from reform measures to make ports more competitive and to attract investment from private and international companies.

The world’s industrial supply chains tend to operate cross-border continuously. However, Taiwan is an export-oriented country, once the supply chain broken down by natural disasters or human error, not only the supply chain would be in risks but also the national transport logistics system and economy would suffer from irreparable losses. Therefore, it is important for companies and governments identifying, assessing and managing risks to detect and prevent the potential hazard earlier. In order to strengthen the maritime logistics system, we aggregated maritime logistics risk management literature, using risk management framework for maritime logistics system to inspect and study the whole maritime logistics system to realize which risk factor needed to be prevented first and draw different results from the research. Through the failure mode and the effects analysis of risk analysis in the first stage, we selected the risk factors by using risk priority number, we then used the analytic network process method to evaluate criteria, risk cause and risk factors in the second stage. Eventually, we got the order of importance of risk factor evaluated by experts and two main results were concluded. First, the weights of assessment guidelines are varying. Experts and Scholars who participated in this study recognized the importance of the assessment guidelines are arranged sequentially as follows: the severity (S), the degree of detect (D), the frequency (O). It is slightly different with common measurement of the frequency and severity. Second, the result shows the first risk factors needed to be prevented is dangerous risk. The rest of risk factors which needed to be prevented are arranged sequentially as follows: information platform for the engine room damage, shipping companies suspended, tsunami affecting navigation, car accident, the ship fails, ship classes suspended, the ship was cross-border attacks, Customs information system hacked and Vessel aground. According to the result of our research, companies and government could achieve risk prevention via the two-stage research methods and strengthen the supply chain.
